DELL PowerEdge R650xs 1U Rack Server 2x Xeon Silver 4316 2.3GHz 20 Core 256GB DDR4 8x 1.8TB SAS H745 2x 1400W

Dense 1U compute for virtualisation and analytics

The Dell PowerEdge R650xs packs two Xeon Silver 4316 20-core processors running at 2.3 GHz with 3.4 GHz turbo into a single rack unit. 256 GB of DDR4 2666 MHz registered ECC memory across eight slots supports heavy multitasking. Eight 1.8 TB 10K SAS drives on a PERC H745 controller with 4 GB NV cache provide fast redundant storage. A dual-port 10 GbE SFP+ OCP 3.0 adapter and iDRAC9 Enterprise complete the feature set for dense cloud or HPC clusters.

Thermals and power in a 1U chassis

Dual 1400 W platinum hot-swap power supplies share the load and keep the server running if one unit fails. The 1U form factor relies on high-speed internal fans to move air across both CPUs, memory and the drive cage, so inlet temperature must stay within Dell specifications. Power draw scales with CPU utilisation and drive activity; the redundant design ensures no single point of failure for either power or cooling.

Build integration and expansion limits

The server occupies one rack unit and ships with ready rails and a front bezel for quick installation. Eight 2.5-inch bays are filled with the supplied SAS drives, leaving no internal hot-swap slots free unless drives are removed. The OCP 3.0 mezzanine slot is used by the 10 GbE card, and the PERC H745 occupies a dedicated internal connector. Buyers needing more than eight drives or a second OCP adapter must look elsewhere.
